Water based curing agent and sealer
Aardcure WBS is high performance and versatile acrylic modifed emulsion curing membrane. When applied to freshly poured concrete, Aardcure WBS meets AS3799 requirements and exhibits excellent durability as a concrete sealer and primer for cementitious surfaces.

Drying time is dependent on the temperature. The sealer is usually touch-dry in approximately 30 minutes at 25˚C. Protect the sealed surface from rain, water and sprinkler systems for a minimum of 6 hours - 72 hours is preferable. Accessible to foot traffic after 4 hours and vehicle traffic after a minimum of 12 hours.
Coverage to meet AS3799 moisture retention is 5m² per litre per coat. Coverage for a single coat application is 100m² per 20 litre drum. The properties of the substrate such as porosity and profile will influence the coverage rate and number of coats required. Subsequent application as a sealer can be applied at 7-10m² per Litre.
Areas to be treated must be clean, dry, free from sawcutting debris.
Apply Aardcure WBS undiluted to the surface.
After surface finishing the concrete must be free of bleed water and sufficiently set to be firm and able to be walked on without marking or damaging the surface.
To achieve stated curing efficiency Aardcure WBS must be applied on the day of the pour and not left overnight.
Care must be taken not to apply thick coats as excessive build may cause the film to blush when subjected to ponding which may be unsightly.
Assess the application area so that a fixed volume of mixed material can be applied over a fixed area to determine the correct application rate.
Agitate the material until thoroughly mixed to ensure effective curing properties.
Effective application temperatures are between 10ºC and 35ºC.
Application is recommended via low pressure spray unit. Spray at a sufficient rate to achieve consistent coverage in even coats. A short nap roller can also be used for smaller applications.
Subsequent application as a sealer can be applied at 7-10m2 per Litre. Apply the second coat in the opposite direction to the first.
